NTS to Conduct Advanced Arresting Gear and Electromagnetic Aircraft Launch System Testing for General Atomics

November 24, 2009

National Technical Systems, Inc. (Nasdaq: NTSC) (NTS), was awarded contracts by General Atomics (GA) Electromagnetic Systems Division (EMS) of San Diego, Calif. for the performance of electromagnetic compatibility (EMC and environmental testing for the Advanced Arresting Gear (AAG) and the Electromagnetic Aircraft Launch System (EMALS).

NTS, under contract to GA EMS, supports environmental qualification testing at GA’s EMS manufacture and test facility at Tupelo, Miss. Some of the tests are being conducted at Joint Base McGuire-Dix – Lakehurst, N.J., where full-scale EMALS and AAG systems are installed and qualified by GA- EMS and the Navy. The EMALS and AAG customer is Naval Air Systems Command (NAVAIR).

NTS will provide environmental and EMC test engineering and evaluation for AAG and EMALS systems to be installed on CVN 78. Testing will be conducted at both the major assembly and component level. Additional testing will be conducted at NTS laboratories located in Santa Clarita and Fullerton, Calif., Boxborough, Mass. and Tinton Falls, N.J. NTS resources support the testing and evaluation program over the next two years.

The EMALS system consists of a high-voltage transformer rectifier manufactured by Neeltran, high power inverters manufactured by GA EMS, a large motor generator, to store energy, manufactured by Kato, and a rectifier manufactured by L-3 Pulse Power Division. Four linear induction motors manufactured by GA EMS will accelerate the launch aircraft from a dead stop to about 150 knots in 3 seconds or less.
